You have authority to enter the main track in CTC territory at a hand operated switch. After you line the switch, the non-controlled absolute signal protecting the main track shows Stop. How will you pass the signal and enter the main?

• A. Pass the signal and enter the main with caution
• B. Stop before entering block. No need to contact dispatch.
• C. Proceed through the Stop signal at reduced speed
• D. Call dispatcher before entering the block

Answer: (B)

The main idea is that a Stop aspect on the protecting absolute signal means you are not cleared to enter the main track block, even if you have lined up the switch. You must stop before the signal and await proper clearance. In this situation, you should stop before entering the block and stay there; you do not proceed or pass the Stop signal.

There’s no need to contact the dispatcher just to stand at Stop. You would only seek dispatcher permission if you needed to pass a Stop or obtain new authority to enter when the signal is not clear. Since you’re required to stay behind the Stop and wait for clearance, stopping before entering the block is the correct action.
